Snapshot 20070307
by Taco Hoekwater 10 May '12

10 May '12

Hi all, I decided to do a snapshot now instead of waiting for friday, because I want to start concentrating on something else besides font support issues. What's new: * Non-CID PostScript-based Opentype fonts are now combined over the entire document, and properly subsetted. The code is borrowed from xdvipdfmx with some minor adjustments Adding support for CID-keyed OpenType fonts would not be hard but at the moment I lack example input (and incentive). * A small extension to the virtual fonts structure: you can use f.fonts[1] = { 'id' = 38} to do a backreference to a previously defined font. This saves quite a few computations * There was a bug in the handling of \leaders in the output whereby it's width was taken to be twice what it should be while writing to the PDF, fixed now. * The font inclusion code is cleaned up a bit by Hartmut. * Some compilation problems were fixed. * There is (quite a bit of) debugging information printed out when OTPs are in use, because I am tracking down a bug reported by Idris. The input of each and every OTP step is shown on the terminal in a line line this: [57902][1568][58423][1568][58408][1568][58921] those are the decimal values of ocp i/o characters. If you don't need them, don't worry about it. Happy TeXing, Taco ----- Downloading and installation details: If you go to https://foundry.supelec.fr/frs/?group_id=10 you will see that there are three new released files: * luatex-snapshot-20070307.tar.bz2 This is the source tree. * luatex-snapshot-20070307-win32.zip A cross-compiled (mingw) windows binary. This is a web2c based binary, so it needs a texmf.cnf file (It will NOT work if you have only miktex installed). * luatex-snapshot-20070307-linux-i386.tar.bz2 An intel 32 linux binary (2.6.17)

A native support for SVG
by TeXWorld 18 Apr '09

18 Apr '09

Hello, I'm a ConTeXt (and LaTeX too) user. When I want to make a vector picture, I'm trying most of the time to use programs who can export PGF/TikZ or PStricks. A lot of users like me don't "program" their vector pictures and use wysiwyg programs like Inkscape or Illustrator to generate PStricks ou PGF/TikZ code. Of course whatever program used, we can find a SVG export. SVG is the most spread and the most used format to store vector pictures. I request a native support for SVG in XeTeX and in LuaTeX, I think it would be a great thing. Of course when I want to include SVG pictures in my documents I can convert them to pdf before but the problem is that labels and texts won't be compiled : fonts will be wrong. What do you think about this ? Do you think it's something possible ?

Unicode in \pdfinfo
by Khaled Hosny 03 Jul '08

03 Jul '08

\pdfinfo doesn't seem to support Unicode, when I compile the attached example with luatex I get symbols like Ù‡ØµØ© instead of the proper (Arabic) Unicode strings. Shouldn't luatex default to Unicode here too? Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

Luatex beta 0.28.0 released
by Taco Hoekwater 30 Jun '08

30 Jun '08

Hi all, I have just uploaded the archives for luatex 0.28.0, another intermediate release leading up to TUG 2008. This release matches SVN revision #1357. There is one new feature: There is now experimental support for non-trivial discretionaries following explicit hyphens. In analogy to \prehyphenchar and \posthyphenchar, there are two new parameters \preexhyphenchar en \postexhyphenchar. Both new parameters default to zero (nothing). When set to a nonzero value, the parameter is added to either the pre- or post- break text. Note that this is *in addition to* the hyphen already in the input. Testing and comments are very welcome. Here is a short example (no idea what is says): \pdfoutput=1 \hsize=2in \postexhyphenchar=`- Seria bom se eu pudesse t\^e-lo mantido como amigo, mas por mais bem-intencionado que eu fosse, n\~ao foi possivel \bye Bugs fixed compared to 0.27.0: * Words that started off with a character with a zero \lccode were never hyphenated at all. * There was a bug in the new active characters code that prevented the latex format from being built (with Invalid character error). * There is a temporary fix for the sometimes appearing "Font has a bad FontBB" message from Acrobat. * \leaders did not actually stretch enough (the last bit of glue that has to line up the line endings was never output to the PDF). * Bad paragraph-related callbacks could result in luatex crashing. * The pre_linebreak and post_linebreak filters were never called when \output was active (this was a leftover of a superceded optimization). * 'skipping' language codes when setting up \patterns c.s. did not work (it used the next empty slot instead of the actual value of \language). * Using multiple 'attr' keywords on box items could cause random crashes. * Calling lang.hyphenate() with one argument (without specifying a tail node) could crash. * The luatex pdf banner and version reporting is cleaned up a bit. * Conflicting patterns inside \patterns now give an error: ! Conflicting pattern ignored. (duplicate identical patterns are ignored without error). The archives (source and binaries) can be downloaded from supelec, as usual: http://foundry.supelec.fr/projects/luatex/ Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Inkscape can embed Type1 fonts in its PDF output, some thing like "inkscape --export-pdf=file.pdf --export-embed-fonts file.svg", but I didn't try it. Another way is to convert text to paths "--export-text-to-path". Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

Hyphenation of "(regarding"
by Jonathan Sauer 25 Jun '08

25 Jun '08

Hello, take the following PlainTeX file: %&luatex \lccode`\(=0 % Just to be on the safe side \showhyphens{regarding} \showhyphens{(regarding} \showhyphens{regarding)} \bye This results in: This is LuaTeX, Version snapshot-0.25.3-2008060319 (Web2C 7.5.6) (hyphenOther.tex Underfull \hbox (badness 10000) in paragraph at lines 5--5 [][] \tenrm re-gard-ing Underfull \hbox (badness 10000) in paragraph at lines 6--6 [][] \tenrm (regarding Underfull \hbox (badness 10000) in paragraph at lines 7--7 [][] \tenrm re-gard-ing) ) (see the transcript file for additional information) No pages of output. Transcript written on hyphenOther.log. Time elapsed: 1 seconds. It seems that the "(" -- but not the ")" -- is treated as part of the word, even though its \lccode is zero. What am I doing wrong? Thanks in advance, Jonathan

Luatex beta 0.27.0 released
by Taco Hoekwater 24 Jun '08

24 Jun '08

Hi all, I have just uploaded the archives for luatex 0.27.0. This is an intermediate release leading up to 0.30.0, to be released around TUG2008. There are just too many changes to wait another month :-) Bugs fixed compared to 0.25.3: * Unicode reencoding support for non-standard (i.e. older) Type1 fonts is now somewhat less broken than it was (#25) * .vf fonts using specials crashed luatex * luatex would crash on --\par (#33) * An attempt is made to get a sane default value for StemV in the created pdf (#32) * We can now guarantee that %PDF-1.* header is printed before the first pdf.print() output * lang.hyphenate() was broken * insert_before(a,a,b) was broken (#37) * argv[0] is now cleaned up before being used as a default for mem_name and prog_name (#28). * luatex would crash on loading extended fonts (fonts loaded via lua callbacks) from a format file. * The fix for pdftex bug #799 is backported from pdftex 1.40.4. * slnunicode had a bug in the unicode.utf8.gmatch iterator. * Queries of nonexisting fontdimens could cause a crash. * luatex would crash on {\textdir TLT\pardir TLT x\break\par } * Fixed wrong placement of lines in mixed-direction paragraphs that could happen in some situations. Other news: * Luatex now includes luasocket (#35) See http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/ for usage. There is a new commandline option: --nosocket to disable this, and that is also implied by --safer. NOTE to the binary builders: there are some unfixed configure problems when you need to add a specific library to get socket support on your platform. You probably will have to edit the generated Makefile by hand (search for 'socketlib'). * There is ongoing development to the 'img' and 'mplib' libraries. See the reference manual for details. * The 'character commands' in virtual fonts now support image inclusion. See the reference manual for details. * Lua error messages now include the call stack. * \directlua and \latelua have been extended to accept a 'name' keyword. The argument is a token list that is used as the lua name of this chunk in lua error messages and call stack prints. (#42) * The lua chunk names can be interfaced via a new virtual table called lua.instancename, the values in that function as defaults in the absence of 'name' keywords. * The 2-plane limit on active character range is removed (#12). * Subsetted TTF fonts in the PDF now retain the cmap table. * There is a new Lua variable os.selfdir. This contains the full absolute pathname of the directory that the executable resides in (with symlinks resolved) * There is a new function os.uname() this returns a lua table containing various platform information items. * The node library now uses text strings for direction specifiers instead of numbers. See the reference manual for details. * The 'E' (edit) as error response functionality is now a noop. * Adding luatex 0.25.3 to texlive resulted in a few minor backports, in particular: Support for mktexfmt is added, and luatangle now identifies itself as such (instead of calling itself otangle). * We fixed a whole series of portability problems (but we probably introduced new problems as well). * Most (all?) files now have a corrected Copyright header, and link in $Id$ and $URL$ into the object file. * Some unnecessary files were removed from the distribution. The archives (source and binaries) can be downloaded from supelec, as usual: http://foundry.supelec.fr/projects/luatex/ Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
